So sal stretched for about 5 min. each day in 5 days and he jogged for about 43 min ..how??
I divided 215 to 5 and I got 43 min. and how did I get 215 well 240 minus 25 min is 215
and elena she stretches for 75 min in the whole 5 days total and 300 minus 75 is 225. then 225 divided by 15 is 15
Sam jogged for 43 min a day and elena jogged for 15 min a day
I hope this helps :)
Let x represent number of redwood trees and y represent number of spruce trees.
We have been given that a park ranger bought 12 trees. We can represent this information in an equation as:


We are also told that redwood trees cost $24 each, so cost of x redwood trees would be
.
Each spruce tree costs $16, so cost of y spruce trees would be
.
Since the park ranger spent $208 on trees, so we can represent this information in an equation as:

Upon substituting equation (1) in equation (2), we will get:







Therefore, the park ranger bought 2 redwood trees.
Upon substituting
in equation (1), we will get:

Therefore, the park ranger bought 10 spruce trees.
First find how many units of solution there is:
500* 2% = 500(.02) = 10 units
You need 10 units of solution in 'x' units of a 10% solution.
x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100
100 units are needed
The symmetric property of congruence states that if a quantity, say, A is congruent to a quantity, say B, then, the quantity B is congruent to the quantity A.
Mathematically, this statement of the symmetric property of congruence can be written as:
If
, then
.
Applying this symmetric property of congruence to the question that we are given, we see that only Option D fulfills the conditions of the definition of the property of congruence as Option D clearly states that:
If
, then
which is the exact statement of the symmetric property of congruence when applied to triangles.
Thus, Option D is the correct option.
